' AUXILIARY-LOOKING MEANS FOR vAUL'rs.

Specification of Letters Patent.

Patented Aug. 532, 1922.

Application filed January 20, 1922. Serial No. 530,577.

To all whom it may concern- Be it known that I, CHARLES W. BABCOGK, a citizen of the United States of America, and a resident of lVaterloo, Blaclthawk County, Iowa, have invented certain new and useful Improvements in Auxiliary Locking Means for Vaults, of which the following is a specification.

My invention relates to improvements an auxiliary locking means for vaults, safes and the like. The object of my improvement is to supply additional locking devices associated with the usual lockingbolts and combination-lock on a vault or safe door, certain parts being placed in close apposition to the lock and to a vulnerable region of the door to either become terminally displaced or broken when the lock is forced or when such .vulnerable place is affected by a high degree of heat, to thus release movable locking means from tension, and prevent releasing of the usual locking elements. This renders the door invulnerable to violent intrusions by burglars or others.

This object has been attained by the means which are hereinafter described and claimed and which is illustrated in the accompanying drawings, in which Figs. 1 and 2 are like fragmentary elevations of the inher face of a vault or safe door and of its locking elements, showing my improved auxiliary locking means applied thereto for automatic actuation when attacked, Fig. 1 being a representation of the auxiliary devices as positioned and tensionally set out of locking engagement, and F 2 showing the released positions of the parts of the devicewhen certain parts are displaced or broken. Fig. 3 is a side elevation of the connected locking elements of the device in untensioned condition, with parts sectioned or broken away and on a larger scale, and Fig. 4c is an under plan View of the same, also with parts sectioned or broken away. Fig. 5 is across section of said device taken on the broken line 5-5 in Fig. 3.

Similar numerals of reference denote corresponding parts throughout the several views.

21 represents part of a door of a vault or safe having on its inner face a fixed marginal strip or rib 26 whose outer edge is flush with the outer-edge of the door and near the jamb part 22 of the adjacent stationary wall of the vault. The rib 26 is orificed in different places transversely parallel with the adjacent face of the door to slidingly seat certain locking-bolts such as one or more bolts 24 of the usual locking equipment, and bolts 12 of my auxiliary locking device, and said rib also has positioned medially between the-latter orifices a threaded bolt-hole to receive the outer end of a headless bolt 1 which is exteriorly threaded terminally and secured at its outer end to said rib by a nut 5. The bolt 24: is secured to a vertical shifting-bar 23, and the latter has a limited play to and from the rib 26 as required in the looking or unlocking-of the door. Inserted in a receiv ing opening or socket in said door and in a housing on the inner face thereof is the usual combination-lock 25 having a lockbar connection with said shifting bar 23. I Referring now to Figs. 3 to 5 inclusive in which is shown the tensionally regulated locking elements of my device, the numeral 3 denotes a cylindrical enlargement cylindrically. and {concentrically formed integrally on the bolt 1 spaced from its inner end, a'nut 2 being mounted on said inner end spaced from said enlargement. A number of like flat rings 4: are mounted loosely upon that part of the bolt 1 which is between the nut 2 and the enlargement 3 and are freely movable relative to each other. As shown in Fig. 5, the hollow of these rings is of greater diameter than said bolt, while the exterior diameter of the rings is the same as the diameter of the enlargement 3. The numeral 7 denotes a cross-bar or plunger-head having a medial cylindrical orifice or bearing seat in which the enlargement 3 is slidably mounted, but this medial orifice is nearer one longitudinal edge of the cross-bar than the other for a purpose to be described. In the same vertical longitudinal plane that traverses the axis of said orifice are parallel cylindric orifices .or seats in opposite ends of the cross-bar 7 in which are mounted the inner ends of the like cylindric lockingbolts 12. In order to releasably secure these ends of said bolts to the cross-bar, both are provided with registering openings 13 to receive short headed pins 14, the latter extremities through the orifices inthe 'rib 26,ithese pins will drop by gravity with their lower ends dependingfromthe bolts to serve as means for; preventing; unauthorized pushing of the bolts back-v out or engagement with the structure 22'. These pins 16 may be pushed up, intovithe' openings 15 before the bolts are withdrawn; and i while setting the device tensionallyi so as to not have anyprojecting parti asqthese openingsvare then concealed within the orifices ofthe-rib 26.

The-numeral 8 denotes a pair of terminally threaded pins or-bracleets positioned above andvbelow thebolt 1' in the same'vertical plane andrhavingtheir inner ends secured in threaded sockets in said crossbar-7. A terminally; orificedi and medially orificed! v cross-bar 9 is mounted to slide from the: m-iddle portionof: the vbolt: l with the outer threaded ends-of the pins Spassedthrough its terminal, orifices and'securedby nuts 10, Astrong coiled spring ll is mounted on the 'middle-partof the bolt 1; andengagedb'e tween said cross-bar 9 and itliezysaid enlargement 3'-of.the. bolt l. A knurled adjusting nut6 is mounted on the outer threaded porrib $26. 7 1

In the: lower end of the cross-bar 7 is drilled a-vertical'hole 19 to receive the upper part ofthe. stemof a hook-17 said stemalso traversing an opensocket or, pit 18 formed in the inner. vertical face of the cross-bar 7: -Elexible ,alined wire sections ZAzare con nected by a turnebuckle 85- for adjusting the tension thereof, the :lower end ofthe lower section 34 beingsecuredlat 831to the inner face, of the door medially below. the; combination lock 25,- saidsectionabeingrcarried medially across the lookcontactingly. and obliquely over aihoused sheave or pulley32 which prevents: lateral swinging i of the, section; The-other section 8 l is carried over arpulley- 31 then'vertically, upward and has a terminal loop passedqover said hook '17. Anotherflexiblewire, made up of twozsections 28 has. its sectionszlikewise adjustably connected by: a turn-buckle 36' depending vertically from andhaving its upper end passed over'apulley 27 with a terminal loop passed; about that part of the stem-ofnsaid hook 17 which is within the pit or-socket:18. The lower end-of thew-ire 28 is fixedly secured at 30 -toithe inner-face ofsaid door, and thewire has in its lower section apart 29- made of easilyfusible material and which tioniofthe bolt lto adjusta-bly, engage said cross-bar 7 to the left, wherebysaidrings 4 are received within the medial orifice of "said cross-bar while simultaneously, the

other crossbar 9 places the spring'll under compression. As previously mentioned, the gravity-pins 16 should be lifted manually before the cross-bar 7 is so shifted. The stem of'the hook 17has a close enough fit inthe hole 19'so as to require a slight amount of force to -withdraw it. As shown iii-Fig 1, the looped upper endof the wire 28 should be inserted in the socket'or pit 18 before the hook 17 is inserted and-after the cross-bar 7 has been moved against the stopnut 2, whereby thewire 28 is placed under tension and also the coiled spring 11 is held undertension, while the hook I? is so clasped as to only be withdrawn as above stated by a reasonable amount of-for'ce applied to it. The upper looped'end of the otherwire 34:

is then mounted upon the hook 17, in both cases said wires being kept under some strain by the use of'the turn--buckles 85 and 36 as maybe suitable to keep the lower wire parts in juxtaposition to the adjacent lock and door-structures. As thus set the deviceis quiescent and do'esnot interfere with the usual operation of the locking means on said door.

In case thepart 25 of'said-combina-tion lock is forced inwardly from its housing, it forces the lower part of the wire 34 away from the :door so that the considerable strain upon the hook 17 pulls'the-latter out thus also freeing the upper part or loop of the other: wire 28; sris thisreleases the coiled spring ll, the reaction of the latter pushes outwardly the cross-bars- 9 and 7 together with the locking-boltsl2 to the lockingpositions shown in' Fig. 2. The outer ends of the bolts 12 then project over the jamb 22, and as theheaded pins-16 drop'b'y gravity, are preven-ted from being pushed back. As the cross-bar 7 hasa greater width between the bolt 1 and enlargement 3 and its outer vertical edge than on the opposite side, this additional width of the bolt is positioned in the plane of the-bar 23 and engages and locks same. It will be understood, that said bolt 1 and attached elements are positioned between the -bar 23 and the door 21. r

In case an attempt is made to use anoXyacetylene torch or other heating means to burn through a vulnerable'part of the door such as that in juxtaposition to the comthefusible part-29 releasing the wire 28so asesae that the spring 11 may react to lock said auxiliary device, the hook l7 pulling out simultaneously.

It is to be understood that various moditications may be made in my device without 'departing from the principle of the invention, and that the same may be applied for locking purposes to any structure where its use is admissible.

It should be noted that when the or ssbar 7 is released from tension and moves back over the enlargement 8, one or more of the rings i is uncovered and dropped down to an eccentric position relative to the bolt 1, and in this position prevents forcing back of the cross-bar. This locking action will occur if the cross-bar moves only enough to uncover a single ring 4.

After this device hasbeen looked as a result of some interference as hereinbefore mentioned, it can be released by an operative who is familiar with the location of the diiiferent structures thereof, by drilling a hole through the door at either end of the bolt 1 to permit of insertion of a small tool which can be used to push around either lock-nut 2 or 5 to remove it.
